--strict-warnings started showing warnings for this today...

Surely an error should be raised if these reads fail?

The -use_srtp s_client/s_server option is supposed to take a colon
separated string as an argument. In master this was incorrectly set to
expect a filename.

Use the PACKET API for processing ClientCertificate messages

Reviewed-by: Tim Hudson <tjh@openssl.org>

Some of the PACKET functions were returning incorrect data. An unfortunate
choice of test data in the unit test was masking the failure.

The move of CCS into the state machine was causing make errors to fail. This
fixes it.

Reviewed-by: Tim Hudson <tjh@openssl.org>

The move of CCS into the state machine introduced a bug in ssl3_read_bytes.
The value of |recvd_type| was not being set if we are satisfying the request
from handshake fragment storage. This can occur, for example, with
renegotiation and causes the handshake to fail.

Continuing on from the previous commit this moves the processing of DTLS
CCS messages out of the record layer and into the state machine.

Reviewed-by: Tim Hudson <tjh@openssl.org>

The handling of incoming CCS records is a little strange. Since CCS is not
a handshake message it is handled differently to normal handshake messages.
Unfortunately whilst technically it is not a handhshake message the reality
is that it must be processed in accordance with the state of the handshake.
Currently CCS records are processed entirely within the record layer. In
order to ensure that it is handled in accordance with the handshake state
a flag is used to indicate that it is an acceptable time to receive a CCS.

Previously this flag did not exist (see CVE-2014-0224), but the flag should
only really be considered a workaround for the problem that CCS is not
visible to the state machine.

Outgoing CCS messages are already handled within the state machine.

This patch makes CCS visible to the TLS state machine. A separate commit
will handle DTLS.

Provide more robust (inline) functions to replace n2s, n2l, etc. These
functions do the same thing as the previous macros, but also keep track
of the amount of data remaining and return an error if we try to read more
data than we've got.

Commit e481f9b9 removed OPENSSL_NO_TLSEXT from the code.

Previously if OPENSSL_NO_TLSEXT *was not* defined then the server random was
filled during getting of the ClientHello. If it *was* defined then the
server random would be filled in ssl3_send_server_hello(). Unfortunately in
commit e481f9b9

 the OPENSSL_NO_TLSEXT guards were removed but *both*
server random fillings were left in. This could cause problems for session
ticket callbacks.
